HERMETIC MOUTH-PIECE FOR MAIL -BAGS.

SPECIFICATION forming part of Letters Patent No. 398,580, dated February26, 1889.

Application filed April 10, 1888. Serial No. 270,184. (No model.)

To (all whom it may concern:

Be it known that I, EVERETT D. MOORE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Hermetic Mouth-Pieces and CombinationsThereof; and I do declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appcrtains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in hermetic seals, and isparticularly adapted for the mouth or opening of a; waterproof bag,especially a mail-bag.

It may consist of metal or some other suitable material, and ispreferably so constructed as to be light in weight. Ipreferably employ abuoyant mail-bag in combination with said mouth-piece, and preferablyplace a protecttin sack over the same. To make said bag buoyant Ipreferably place an annular chamber or chambers either on thewater-proof bag or the protecting-sack, which may be filled with air,gas, cork, or any buoyant materialpreferably cork.

For further description of my i nvention, reference is had to theaccompanying drawings, in which Figure 1 is a view in perspective of thebag inverted. Fig. 2 is a sectional inverted view showing interior ofbag. Fig. 3 is a pespective view of the plate or cylinder to which thebags are fastened. Fig. 4 is a perspective "view of the removable heador cover; Fig. 5, a sectional elevation showingremovable head secured tothe plate, to which may be fastened the canvas or waterproof bags, orboth.

Similarletters refer to si milar parts throughout the several views.

The bag or pouch may consist of two partsan exterior part, A, and aninterior part, B, the mouths of which lap each other and are secured byrivets or screws to the plate 0, Figs. 1, 2, and The exterior part,A,ismade of some pliable material, as canvas, duck, or hide, and ispreferably provided with annu lar chambers A A, which are preferablyfilled with corkpreferably ground cork or some such buoyant substancefor the purpose of floating thebag. A handle orgrip, A may be secured tothe bottom to facilitateitshandling. The interior part, B, is made ofsome water-proof materialsuch as oil-cloth or rubber or water-proofedcanvas-aud forms the receptacle for the matter to be carried. The monthsor ends of the bugs A and. B are clamped to the plate C by the ring D,which is securely held by rivets or screws, as shown, making an air andwater proof joint.

The removable head consists of the plate E, to which are firmly securedthe carriers E, which hold the rollers 6. One or severalthickncsses ofcanvas or duck, G, maybe stretched over this plate and clamped securelyby means of the ring E which is riveted or screwed on, as shown. Achain, ll, couples the removable head to the plate C. This plate hasopenings C, which admit the carriers E of the removable head to enterand brings the rollers in contact with cam-ridges C Figs. 2, 3, and 5.By now turning the removable head in the right direction it is firmlypressed to the plate 0 by means of the rollers c ascending the camridges0 A gasket, K, Fig. 5, which maybe fastened to the removable head or theplate 0, or just placed between, may serve to make thejoints moreperfectly air-tight and water-proof. Staples S S are provided on theplate 0 and removable head E for the purpose of attaching a lock.

The outer or protecting bag may be dispensed with and the chambersattached to or constructed in the waterproof bag; or the chambers may beentirely dispensed with, so that the bag will consist merely of awaterproof bag and its hermetically-sealed mouthpiece.

Having described my invention, what I desire to secure, and claim byUnited States Letters Patent, is-

1. In a hermetic mouth-piece for mail-bags, the combination of ametallic ring, to which the bag is secured, the lower edge of which iscut into two or more inclined planes, and a cover of about the same sizeand shape as the ring and arranged to rest upon it, and provided on theside next the ring with two or more hooks set rigidly into the cover andadapted to engage the inclined planes of the ring, whereby the cover andthe ring are pressed closely together when the cover is turned,substantially as described.

'2. In a hermetic mouthpiece 'for mail-bags, the combination of ametallic ring, to which the bag is secured, the lower edge of which iscut into two or more inclined planes, and a cover of about the same sizeand shape as the ring and arranged to rest upon it, and provided on theside next the ring with two or more hooks or carriers set rigidly intothe cover and provided with friction-rollers attached to them andengaging the inclined planes of the ring, whereby the, cover and thering are pressed closely together when the ring is turned, substantiallyas described.

In a hermetic mouth-piece for mail-bags, the combination of a metallicring, to which the mail-bag is secured, the lower edges of which areprovided with a downwardly-projecting flange cut into two or moreinclined planes, a cover of about the same size and shape as the ring,and provided on the side next the ring with two or more hooksset'rigidly into the cover and adapted to engage the inclined planes ofthe flange, anda gasket interposed between the ring and cover,- as andfor the purpose specified.

4. In a hermetic mouth-piece for mail-ha 's, the combination of ametallic ring, to which the bag is secured, cut with slots or ways topermit the hooks or carriers to pass through it, the lower edge of saidring being cut into two or 'more inclined planes, and a cover of aboutthe same size and shape as the vring and arranged tore 3131113011 it,and provided on the side next the ring with two or more hooks setrigidly int-o thecover and adapted 'to :engage the inclined planes ofthe ring, whereby the cover and ringare pressed closely together whenthe cover is turned, substanti'ally' as described.

5. Inahermeticmouth-piece for mail-bags, the combination of a metallicring, to which the bag is secured, the lower edge of which is cut intotwo or more inclined planes, and a cover of about the same size andshape as the ring and constructed of two rings of metal, between whichis-riveted a sheet of flexible water-proof material and arranged to restupon the bag-ring, and provided on the side next to thebag-ring, withtwo or more hooks set rigidly into the rim of the cover and adapted toengage the inclined planes of the ring; whereby the cover and the ringare pressed closely together when the cover is turned, substantially asdescribed.

6. In a hermetic mouth-piece for mail-bags, the combination of ametallic ring countersunk on the inner edge and provided with a gasketresting in said countersunk space, and having a downwardly-projectingflange the lower edge of which is out into two or more inclined planes,and a cover of sucha size and shape as to'fit the countersunk space inthe ring and rest upon the gasket, and having hooks provided'withrollers secured to the sides of the cover next the ring and adapted toengage the inclined planes of the flange, whereby the cover and thegasket will be pressed closely together when the cover is turned,substantially as described.

7 The combination of a hermetic mouthpiece consisting of a metallic ringprovided on its lower side withinclined planes, a cover provided on theside next the ring with means adapted Ito engage the inclined planes andpress the ring and cover together when the cover is turned, and awater-proof mail-bag secured to the ring, whereby the bag may be sealedso as'to be Water-tight.

lnitestimony whereof ,I affix my signature in presence of two witnesses.
